13.5 = x
Option B
The sum of the measures of the exterior angles of a 53 - gon is 360 degrees
<em><u>Solution:</u></em>
The formula for sum of exterior angles "n" is:
Distribute 180
Therefore, sum of measure of exterior angles is 360 degrees
<h3>Sum of the measures of all the exterior angles of any polygon, irrespective of its number of sides is always 360 degrees</h3>
Thus, in a 53 gon, sum of measure of exterior angles is 360 degrees
